| Neuron | a nerve cell |
| Axon | is a single long fiber that carries impulses away from the cell body |
| Central Nervous System | includes the brain and spinal cord |
| Peripheral Nervous system | is made up of the nerves that lie outside the system |
| regulation | is the life process by which cells and organisms respond to changes within and around them |
| Nerve cell | the basic unit of the nervous system |
| dendrites | are branched parts of a neuron that receive impulses from other neurons or sense organs. |
| cell body or cyton | contains the nucleus and cytoplasm |
| ganglia | cell bodies often are present in groups |
| synapse | between the dendrites of one neuron and the axon of another is a space |
| nerve | is a bundle of neurons or parts of neurons |
| sensory neuron | carries impulses to the central nervous system |
| motor neurons | carry impulses from the central nervous system to various body parts such as muscles or glands |
| mixed nerves | contain both sensory and motor fibers |
| reflex | is an example of involuntary behavior |
| reflex arc | in a reflex response nerve impulses travel in a set pathway |
| interneuron | connects the sensory neuron with the motor neuron |
| cerebrum | controls movements the sense speech and abstract thought |
| cerebllum | coordinates the actions of muscles and helps maintain balance |
| medulla | controls involuntary actions such as breathing and heart beat |
| glands | produce hormones which are directly secreted into the blood |
| hormone | chemical messenger |
| steps | sensory system, interneuron and motor system |
